Such nights are possible, and we survive them. It is a matter of sleeping next to the adored body you no longer have the right or inclination to love. Whether you are the one who casts off, or are the cast of yourself; whether your arms are the recoilers, or the ones that reach wantingly, then pull back, remembering they are no longer wanted. Two bodies that are used to each other's rhythms and sleep sounds, that know the turnings and breathings, know not to worry about that cough or that brief garbled grunt, that wildly flung arm or that stone-cold foot. Bodies that soon will not know each other's night selves: will touch each other through jackets and jeans and the cooled-down air of reestablished acquaintance, if such a thing is possible between a given pair of ex-lovers.
